PLAN B AND BLEEDING

Beatrice

Please answer me. I started my period the 28th of December and i thought it ended a 4 days later and i had unprotected sex for the first time but then me start bleeding again. But I’m stupid and got paranoid so just to be sure I took a plan b about 10 hours later that night.My period ended a couple days later , and it’s been about 5 days now since I took the pill and I’m bleeding again? What’s goin on? Its like I’m on my second period of the month
